REEL

Filed May 20. 1927 INVENTOR BY WW. ATTORN Patented Feb. 9, 1932 UNITEDSTATES PATENT OFFICE llAIRlL E. ANDERSON, 01! EAST ORANGE, NEW JERSEY,ASSIGNOB TO EASTERN TOOL MANUFACTURING 00., BLOOMFIIELD, NEW JERSEYApplication filed May 20,

This invention relates to an improved reel tor moving picture films andhas for its object to provide a reel that is strong and can be cheaplymade and is open at the sides to it such an extent as to enable accessto ct the roll ct film when it becomes necessary to do so.

Another object oi the invention is to provide a reel with a smooth andeven juncture ill) at the hub and spokes of the reel so that thepossibility of the edges of a film becoming caught in any part of thereel is minimized.

The invention is turther desig' led to provide a reel with the spokesand rim made'up ll"? oil a set ot wire sections which are embedded attheir inner ends in a hub that is cast around them.

The invention also relates to the method of inalring up a series of wiresections which are all placed side by side to complete the side piecesor tlanges and then die-casting the hub around the inner ends of suchwire sections to hold them in their relative positions and to form thecomplete reel.

The invention is illustrated in the accompanying drawings in whichFigure 1 is a side view of a film reel embodying my invention. Figure 2is a section of the central portion thereof but on an enlarged scale,this section being taken 011 a plane indicated by line Q2 in Figure land Figure 3 is a similar section taken on line 3-3 in Figure 1. Figure4; is a side view of one of the wire flange or side-piece sectionsemployed in making the reel illustrated in Figure 1 and Figures 5 and 6are modifications showing how the wire sections can be made to abut toform a relatively continuous flange or side-piece.

Films are wound on reels and require a reel thatwill not provide anyprojections or which the film can catch to interfere with its smoothtravel in a camera or projector and I have devised a reel which is lightin weight and which is provided with side pieces between which the filmis coiled, these side pieces being made up of wire sections. For thepurpose oi illustrating I show one form of section in ll'igure 4consisting of an arm 10 which forms a spolre and a curved arm 11 whichforms a part ot the rim when such sections are arthe sides 1927. SerialNo. 192,828.

ranged side by side as shown in Figure 1 and these sections are thensecured to a suitable hub which acts to hold these sections in place andin addition provides means for mounting the reel on a shaft so that thereel can be rotated.

In the form shown in Figures 1 and 4, the wire sections are madetriangular, the ends of the wire forming one of the angles as at 12which is opposite the curved or rim portion 11 and these ends '12 aresecured to the hub usually by lacing these ends in a die cast machine anthen casting the hub so as to embed these ends in the casting. Such casthub is shown at 13 in Figure 1 and to make the securing of the wire morepronounced I usually offset the inner ends of the radial arms 10 of thewire sections as at 15, the illustration showing a crank-like end,although various other forms of corrugated ends may be used.

I alsofind that the making of the reel is easier by making the hub inhalf sections which are placed face to face and in the drawings I showsuch half sections 16 and 17, each provided with its side-piece made ofwire sections, the half sections being secured together by suitablemeans such as the rivets 18, these being usually placed in the recesses24 of the hub sections, these recesses being made primarily for thepurpose of reducing the weight of the reel. Light rivets may be used asI prefer to arrange keyways or tongue-and-groove faces on the hubsections, one section having projecting parts 20 which fit intocorresponding recesses 21 on the other sections, four of these beingsufficient to show that when the sections are put together theseprojections and recesses interlock and prevent rotated movement of onesection relative to the other and the rivets 18 hold these half sectionstogether. It will be evident that other means of securing these halfsections together may be employed.

In the construction illustrated in Figure 5 I show sections with onespoke arm 10 and the radial arm 11, one end of the radial arm 11 beingbent over as at 22 to rest against the spoke arm of the next succeedingsection in order to make a substantially continuous rim. In Figure 6 Ishow a modification in which the free. end of the rim arm 11 of theprior section is cut as at 23 to fit against the curve of the nextsection, so as to form a continuous rim.

It will be evident that in manufacturing this reel the wire sectionswhich are cheap to make are-assembled and while held in assembledposition have their ends surrounded by a casting and the reel is thencomplete.

It will be evident that various changes can be made in the form of theparts without departing from the scope of the invention.

I claim:

1. A film reel comprising wire sections, each section having two arms,one arm to form :1 spoke and the other arm to form a segment of the rimthese sections being ar ranged side by side to form an annular sidepiece and a hub to which the inner ends of the spokes are secured.

2. A film reel comprising parallel side pieces each formed of wiresections arranged side by side, each wire section consisting of asinglewire with two arms, one forming a spoke and the other a segment of arim, and a hub to which the inner ends of the sections are secured.

3. A film reel comprising parallel side pieces each formed of wiresections arranged side by side, each wire section consisting of a singlewire with two arms, one forming a spoke and the other a segment of arim, and a cast hub in which the ends of the spokes are embedded.

4. A film reel comprising side pieces each composed of wire sectionsarranged side by side, the inner ends of said sections being olfset, anda cast hub in which said elf-set ends are embedded.

5. A film reel comprising a series of sections each formed of a singlewire bent to form a spoke and to form a part of the rim, these sectionsbeing assembled to form parallel side-pieces, and a cast hub in whichthe inner ends of the spokes are embedded.

In testimony whereof I aflix my signature.

CARL E. ANDERSON.
